Nowdays I intend to make a test of my mrf case's result with the paper.But I find the result vary with the different diameter of my rotating size.I made a comparision in two situation in which only the MRF zones size is different.As you can see in the image.(its a slice of a 3D case)

The first one's MRF zone is smaller than the other.expect this everything is the same.But after 2000 iterations,the velocity is a little different.I dont know if it gets convergence but in 2500s iterations,the velocity looks dont change anymore.

Same problem here. When MRFZone limit is near walls ( sometimes it is required because stator zone is quite near) the pressure field around the walls is modified. The pressure lines are modified to accommodate its shape to the limit of the MRF Zone so suction lobe is affected and so all the aerodynamics of the wall (wake,....). The solution is wrong.

I do not have AMI interfaces so the solution proposed does not work.
Did you start a bug report?
